Progressive Web Applications and It’s Benefits

Progressive Web Applications or PWAs as a popular abbreviation, are described as the best of both worlds. What it entails is that the application lives on the website but its functionalities resemble more of a native application. Users are provided a mobile-like experience while navigating through the website. The reasons why everyone calls them as progressive are because of its fast, responsive and connectivity independent feature.

It is possible that one can get entangled in many myths that circulate regarding PWAs. Some of the most common myths are:
• You’ll need JavaScript to build a PWA.
• You need to start with a single-page app to make a PWA.
• It makes more sense for apps your users want to install.
• PWAs work only in Mobile devices.
• PWAs are mainly meant for Android devices.

JavaScript and single-page apps are not a mandated regulation for creating PWAs. They are simply an option, just like for any other web project. Every PWA should have or at least be a website. PWAs hold some more features that allow them to do more things than what a website can do traditionally.

While PWAs do work on mobile devices, it’s not imperative that it should only be limited to small screens. Also, they are not just limited to Google since many other tech giants such as Microsoft, Samsung, Opera, etc have announced their plans to implement PWAs. Because of the contribution of these rumors, many people might be disinclined to use it for their projects. Every site can be and should be a PWA.

The three baseline criteria a site must fulfill to be considered as a PWA are:
• They need to run under HTTPS- PWAs have a vast choice of extra privileges in the operating system, so it is important that the connection be secure.
• Web app manifest is a requirement because it is a JSON file that has much major information regarding the site. One might even have very basic.
• You require a service worker. The Service Cooker Cookbook is an excellent example of one of the many recipe guides out there to create service workers in the career’s shape one wants to pursue.

Once these are put in their place, it will transform the website into a PWA.
